Abstract: Systems and methods can enable the control the motion of an animated character based on imagery (e.g., captured by an image capture device such as a web camera or “webcam”) which shows a person in motion. Specifically, the animated character can be automatically rendered to have the same motion as the entity shown in the imagery (e.g., in real time). According to one aspect of the present disclosure, the animated character can be rendered by iteratively transforming (e.g., including deforming the actual geometry of) a vector-based surface illustration. Specifically, the systems and methods present disclosure can leverage the scalable and transformable nature of a vector-based surface illustration to provide more realistic motion-controlled animation, in which the underlying geometry of the animated character is able to be adjusted to imitate human motion more realistically (e.g., as opposed to basic rotations of fixed character geometry).
